The NBA 2K13 demo is available now on the Marketplace for Xbox Live "GOLD" members (available next week for Silver). Most are getting it by searching for "2K13" or going to Genre ---> Sports and Recreation. You can also queue it up right here.

The PS3 demo arrives later this afternoon, we'll update this post when it's available.

UPDATE: PS3 demo is available now. If you don't see it, search for it.

For the first time since 2k11...I was actually able to beat someone off the dribble (with Westbrook) just by being faster than him. No magical defenders sliding in place, he got beat and was too slow to recover.

Now, the demo lets you change sides between the Heat (who they automatically put you on) and the Thunder.

As for the Online portion it is an Online Quick Match. Presumable it's 1 quarter but I'm having dribble with the dribbling right now. I'm forced to do simple things (A cross or a hesitation), then hold turbo to beat Mario Chalmers .

Oh, and yeah. It's going to take a while to get used to holding the left trigger to get shots off. Feels more natural just to tap X if you want to finish in the lane.

Very glad to hear we have a choice between the Heat or Thunder. This demo can't download any faster!

Awesome experience so far. Got me about 3 games to finally grip the new controls but I still get confused sometimes with the Control and Shot stick.

+ Wade, Lebron, KD and Russ sure do stand out with their explosiveness toward the basket.
+ On-ball defense feels better.
+ Love the physics and collisions.
+ Blocks animations are nice!
+ Post game is gonna be fun. Simpler and more effective controls.

- Tried spamming the steal button and there are times I can easily steal the ball or deflect the ball from the ballhandler.
- Graphics seems to downgrade on some cut scenes like zooming the face of freethrow shooter.

They're fine. I actually prefer an always connected experience.
I'd really prefer an offline way to play, but its not a bother.
I don't really like them, and am more reluctant to buy a game because of it.
I won't buy them. I want my games offline.
